block 10. In the recess a is loosely fitted the rear portion of a dish 11; and at the center of said disk one end of a shaft 12,

is attached, that is loosely fitted in the bore 6 c', and projects therethrough, having a collar 12, thereon, which contacts with the rear surface of the stationary block 10, said shaft, shown broken away, in complete form being extended to and connected with a source of power and rotary motion.

. The front surface 01 of the circular block 10, which defines the de th of the recess a,

is true and parallel wit the level bottom surface of said recess, and upon the disk 7 11, a circular peripheral flange 11, is

i j formed, that loosely contacts with the surface (I, as shown in Fig. 4. In the circular side wall of the recess a, at or near the front face ll of the block 10, an internal gear 0, is formed, said gear being concentric with the axis of the shaft 12. In the disk 11, a proper distance one side of its center,

a circular recess 9, is formed, which extends from the front surface thereof and cuts 30 through the side wall of the same, thus forming an opening in said side wall opposite the internal gear 6.

The recess 9 is diametrically enlarged outside of the gear 6, said enlarged recess y 35 having a depth equal to the thickness of the flange l1. Centrally in the recess 5 a journal pin 13 is formed or secured, the true outer end surface of which is disposed nearly flush with the outer surface of the disk 11..

A spur gear 14, of proper diameter to engage its teeth 0' with those of the internal gear a, is centrally bored as at n, and through said bore is mounted upon the journal pin 13, thus causing the teeth 0' to mesh with the teeth 0.

An annular recess is formed in the outer surface of the spur gear ll. around the llOl't In, said recess race-Wing a. washer plate 15. that is scrlufcd in placc on the pin .12. by a set screw in, as shown in Fig. 4. A. peripheral fian e 14 is formed on the spur gear 14, outside of the teeth w on the latter, said flange occupying the counterl'mrcd enlargement 9' of the recess g, as shown in Fig. 4.

Upon the outer surface of the s )lll' gear flange 14", which is level with a like sur face on the disk flan e 11, a. journal pin H- is formed or secure and projmxts outward in a plane parallel with the axis of the pin 13. On spacing blocks 10". that are portions of the frame 10 which supporls the Ill) I circular stationary block 10, two uide bars l'l al'e mounted and secured at tieir ends, and thus disposed parallel with each other, said guide bars being positioned an e ual distance from the center of the isk flan e 11".

pon the pin 16 a slide box 18 is meanted, the latter having a circular hole In 1t, which loosely receives the pin, and as indicated in Fig. 1, the slide-block is loosely fitted between the guides 17.

The operation is as follows: Upon rotation of the shaft 12 in either direction, the disk 11 will be correspondingly rotated, which will orbitally rotate the spur gear 14, and as said gear is meshed with the statlonary internal gear 6,- it will be evident that the spur gear will be caused to rotate upon the 'ournal pin 13. It will be seen that the com ined rotary movements of the disk 11 and spur ear 14, that are in opposite directions, wilfcause the block 1S to reciprocate in the guides 17, thus converting the rotary movement of the shaft 12 into reciproeatory movement of the block 18. For useful effeet, a pitman rod 19, shown broken, may be employed, that mav be loosely mounted on a pro ected end 0 the pm 16, and said rod may obviously be connected to machinery for transmitting reciprocatory motion thereto.

While the present arranqement of arts shows the guides 17 disposed horizonta ly, it is apparent that they may be arranged vertically or at an incline, without )revent-ing the pro 1' reciprocation of the s ide block.

It wi 1 be noted that the operation of the device may be reversed, that is, if the slide block is reciprocated by applied power, the gearing already described will convert the reciprocatory movement of said slide block into rotary motion in the shaft 12.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination with a rot-atably-supported shaft, and a stationary internal gear concentric with the shaft, of a disk rigid with the shaft and having a recess formed in its outer face at one side of its center, the said recess being enlarged at its outer portion, a journal pin promoting from the bottom of the recess in said disk. a spur gear in said recess and rotatable on the journal pin, the said spur gear meshing with the internal gear and. having a flange fitting in the enlarged portion of llte recess in the disk, a journal pin on the spur gear, and a slidably supported block on said journal pin.

2. The combination with a block sup' ported on a frame, the said block being centrally bored and recessed in one side, of a flanged disk in said recess having a recess formed in its outer wall at. one side of its center and enlarged at its outer portion, a

shaft centrally extended from the disk and passing through the central bore in th block, an internal giur in the recessed block, a journal pin on the dish, a spur gear in said recess in the disk and mounted [in ill pin, the said spur gear nn-shing with the internal gear and having a pcril'iherul flange fitting in the enlarged portion of the recess in the disk, and means for transmitting motion from the spur gear.

3. The combination with a stationary block having a central bore and circularly recessed in one side and an internal gear formed in said recess, of a disk seated in said recess, a shaft extending from the disk and passing through the bore in the block, the said disk having a recess formed in its outer face at one side of its center and enlarged at its outer portion, a spur gear in said recess in the disk and having a peripheral flange outside of the teeth fitting in the enlarged portion of the recess in the disk, a pin arranged eccentricallv on the disk and on which the spur gear is mounted, means for holding the spur gear in position, said spur gear meshing with the internal gear, a pin on the spur gear, and a sildably supported block mounted on said pin.

4. The combination with a circular block supported by a frame, said block being centrally bored and circularly recessed in one side, and an internal gear formed in the circular side wall of the said recess, of a flanged disk seated in said recess, a shaft extenc ing from the center of the disk through the bore in the block, the said disk having a circular recess formed in its outer face at one side of its center and enlarged at its outer portion. the said recess cutting through the side wall of the disk and forming an opening in said side wall opposite the internal gear teeth, a journal pin eccentrically projected from the disk, a spur ear rotatable on said pin and seated in said reccss in the disk, the said spur gear meshing with the internal gear and having a peripheral flange outside of the teeth fitting in the enlarged portion of said recess in the disk, :1 pin on said spur gear at one side of the center, a slide block on said pin, and guides for supporting the slide block.

5. The combination with a stationary block centrally bored and circularlv rcccssci'l in one side. an internal gear formed in the circular side wall of tho recess. a flanged disk seated in said recess. a --lmli extending from said disk through the bore in the block.

a the said disk having a circular rot-( s formed in its outer fin-c at one side of its router and enlarged at its outor portion, llnsaid recess cutting through the side wall of the disk and forming an opening opposite the internal gear. of a spur gum scuhrd in said recess in the disk and meshing will) the internal gear, the said spur gear having a periphblock loosely mounted on said pin, and a air of guide bars carried by [he flul'nu and tween which the. slidu block I'Ql'fil'Jl'OCu has.
